When the Supreme Court ruled that a Christian student group could only be recognized at a small public law school if it accepted non-Christians and gays as potential leaders, some lawyers and campus advocates grew nervous.

While the 5-4 decision in Christian Legal Society v. Martinez was primarily aimed at public colleges and universities, some conservatives say the decision has upended university religious life, with both public and private schools reconsidering nondiscrimination rules.

Now, nearly two years after the decision involving the University of California's Hastings College of the Law, the case is causing strife across U.S. college campuses.
